Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant layout designing method and apparatus, and more particularly, to one or more plant equipments and the like constituting a plant (for example, in the case of a crusher plant, a crusher, a sorting machine, Pile etc.) and connecting devices (eg conveyors, chutes, toys, pipes, etc.) that connect the layout elements so as to meet various constraints and design rules on the target terrain. The present invention relates to a plant layout design method and apparatus for automatically performing a three-dimensional layout design.

2. Description of the Related Art When constructing a plant, it is necessary to design the layout of plant equipment constituting the plant and connecting equipment for connecting them in accordance with the topography to be constructed. However, depending on the plant, the terrain to be constructed is often natural terrain with undulations, obstacles, etc. In that case, the shape of the terrain to be constructed varies from design project to design project. Furthermore, in order to realize it as a plant, it is necessary to consider the characteristics of each of the above-mentioned plant equipment and connected equipment and satisfy many constraints and design rules. Conventionally, the layout design of this plant has been manually performed based on past design results, experience, design rules, and the like.

Therefore, as a system for supporting the above-mentioned manual plant layout design, for example, there is a system proposed in Japanese Patent Laid-Open No. 1-234979. In this system, a plurality of layout plans are automatically created using data on layout areas, data on devices to be arranged, and data on constraints on layout, and design rules are set for the plurality of layout plans. A function of outputting an evaluation value for is proposed, and a layout plan is manually selected and modified based on the evaluation value. Further, in Japanese Patent Laid-Open No. 64-33680, a CAD capable of designing a layout by interactive processing.
For the system layout modification by interactive processing, the system evaluates whether the modification satisfies design rules and constraint conditions and displays a violating part, or a function of limiting the modification. In addition, JP-A-64-
According to Japanese Patent No. 28785, in a CAD system capable of designing a layout by interactive processing, three-dimensional shape data of each plant device is stored in advance, and the 3D shape data of each plant device is stored on a created logical connection diagram. It provides the function to arrange the dimensional shape data. The designer
Through the interactive processing, the arrangement positions of the above-mentioned plant equipments, the arrangements and the three-dimensional shapes of the connecting equipments connecting them are determined.

[0004]

However, when manually laying out the plant as in the above-mentioned conventional technique, it is necessary to consider all the characteristics, constraints, design rules, etc. of each device as described above. Therefore, the design work required abundant experience and skilled technology, and required a lot of time. In addition, even if a part of the layout plan is modified, it is necessary to reexamine the consistency of the entire layout, which requires a lot of time. Further, there is a problem that only the designer himself can easily understand the detailed part of the three-dimensional realization image of the layout-designed plant. Further, in the systems proposed in the above-mentioned JP-A-1-234979 and JP-A-64-33680, whether or not the layout rule or its modification is satisfied with the design rule or constraint condition is evaluated.
The correction based on the evaluation needs to be performed manually in any system, and much time is required in that part.

In the system proposed in Japanese Patent Laid-Open No. 64-33680, the three-dimensional shape data of each plant equipment can be easily created, but like the connected equipment, the terrain and layout of the layout area are arranged. If the shape changes depending on the situation, it must always be manually created. In addition, in the layout design of the plant, the layout of each plant equipment and connection equipment is determined according to the topography after construction, and the layout of the construction equipment is determined after the layout of each plant equipment and connection equipment is determined. However, in any of the above-mentioned prior arts, the latter case is not dealt with.
It needed more time. Furthermore, the cost estimate for plant construction cannot be determined while there are uncertain factors (for example, the length of connecting equipment and the construction surface), and whether it should be done at the stage when the final layout design proposal is made,
There was also the problem that many corrections had to be made. The present invention has been made to solve various problems as described above, and an object thereof is to determine a construction plan in a plant layout design before or after a layout of each device is determined. In both cases, the layout design and estimation by the 3D model of the plant can be performed quickly and automatically, and it is easy for anyone to display and output the layout design result and the estimation result in various ways. It is an object of the present invention to provide a plant layout designing method and device capable of understanding design contents.

A schematic configuration and a schematic operation of the plant layout designing apparatus according to the present embodiment will be described with reference to FIG. First, the terrain input device 1 inputs the data of the terrain serving as the layout area as a set of point coordinate values. The terrain mesh data calculation device 2 creates terrain mesh data obtained by subdividing the terrain from the input terrain coordinate values. In the formation surface input device 3, when the formation surface is determined, the data of the formation surface is input as a set of coordinate values capable of determining the formation surface. Then, the terrain mesh data after the formation is created by the creation computing device 4 using the terrain mesh data and the creation surface coordinate values,
The terrain mesh data after the creation is stored in the layout model storage device 11. At this time, if the construction surface is not input, the topographic mesh data obtained by the topographic mesh data calculation device 2 is stored as it is.

Next, in the placement element designating device 5, all plant equipment is a unit of a plurality of placement elements composed of one or more plant equipment based on the logical connection relation (flow sheet) of the plant equipment. Classify into. In the subsequent layout design, the layout will be considered in units of the above-mentioned layout elements and the connected devices that connect them. In order to map the classified layout elements on the same coordinate system as the topographic mesh data, the layout information input device 6
The layout information including the coordinate values of the reference points and the rotation angles of the layout elements is input, and the layout evaluation is performed by the layout information storage device 8
To memorize. Then, by the arrangement information correction device 7,
The layout information stored in the layout information storage device 8 is evaluated, and the layout information is automatically corrected so that the layout information satisfies the constraint condition and the design standard, and the modified layout information is again stored in the layout information storage device 8. Remember. It is possible to determine the construction surface using the corrected arrangement information, and the formation arithmetic unit 4 can create or correct the topographic mesh data after the formation.

The three-dimensional shape data storage device 9 stores in advance the three-dimensional shape data of each plant device and the connected device, and the three-dimensional model generation device 10 uses the three-dimensional shape data and the arrangement information correction device. A three-dimensional model of the placement element and the connected device after placement is generated based on the placement information modified in 7 and stored in the placement information storage device 8 and the terrain mesh data stored in the layout model storage device 11. . Then, the generated three-dimensional model is stored in the layout model storage device 11 as a layout model together with the terrain mesh data already stored. At that time, the above-mentioned three-dimensional model has a tree-like configuration such as the overall model, the layout elements, each plant equipment, and the shape of each plant equipment, and each has a shape having attribute values such as price and weight. Remembered in.

Further, the group calculation device 13 calculates the similarity between the layout elements stored in the layout model storage device 11 regarding the plane position and the height, and arranges the layout elements having the high similarity into one group. The arrangement elements are classified into a plurality of groups by putting them together, and the obtained group classification information is stored in the group classification information storage device 14. It is possible to determine the construction surface by using the arrangement coordinates of the arrangement elements grouped in the group classification information, and the formation arithmetic unit 4 can create or modify the topographic mesh data after the formation. In the layout model display / output device 12, the layout model stored in the layout model storage device 11 is
Various processing such as hidden line processing and shading processing can be performed to display and output three-dimensionally. At this time, it is also possible to perform processing such as displaying for each group using the group classification information stored in the group classification information storage device 14.

Further, the estimate calculation device 15 retrieves the attribute values of each plant device and the connected device from the layout model storage device 11 and refers to the price database stored in advance to refer to the price and arrangement of each device itself. Calculate the rough estimate for the entire plant from the formulas for the construction and construction costs associated with. The approximate estimation result is displayed and output on the estimation display device 16. Details of each part will be described below with reference to the drawings. Although the crusher plant is taken as the plant for layout design, it can be applied to other plants as well.

First, a method of inputting topographical data will be described. The terrain input device 1 inputs terrain data to be laid out as a set of point-like three-dimensional coordinate values for each contour line. The terrain mesh data computing device 2 generates terrain mesh data represented by an isotropic mesh of a predetermined length unit obtained by subdividing the terrain from the three-dimensional coordinate values for each contour line (see FIG. 2 (a)). . FIG. 2B shows an example of an interpolation method from the contour line data to the coordinate value of each point of the topographic mesh data at that time. From the position X where you want to obtain the height, draw straight lines in two directions that are orthogonal to each other as shown in the figure, and find the positions that first intersect the contour lines A, B, respectively.
Let C and D. And from the height of A, B, C, D, X
The height of X is obtained by the equation in the figure using the ratios of the horizontal distances from A to B, C, and D, respectively. In this way, by converting the terrain mesh data, which is a set of points, into three-dimensional mesh data, 3
Dimensional display and installation coordinate calculation of plant equipment and connected equipment can be easily performed. On the other hand, in the construction plane input device 3, as shown in FIG. 3, the construction plane data including roads is input as a set of three-dimensional coordinate values. Then, the creation computing device 4 creates the created topographic mesh data from the topographic mesh data created by the topographic mesh data operating device 2 and the creation surface data input by the creation surface input device 3. The method is to superimpose the creation surface data on the topographic mesh data, and as shown in FIG. 3, from the coordinate points and the line segments connecting the respective coordinate points constituting the creation surface data, around each coordinate point and each line. With respect to the terrain mesh in the normal direction of the minute, the smooth surface is calculated by performing the smoothing calculation so that the terrain gradient becomes a determined angle (for example, 60 °), and the terrain mesh data is used as the formation surface data. The topographic mesh data after creation is generated by changing the above-mentioned laver surface calculation result. The terrain mesh data after the creation is the layout model storage device 11
However, if the creation surface is not decided in advance,
In other words, if no input is made on the construction surface input device 3,
For the time being, the terrain mesh data before creation is stored as it is.

Next, a method of generating layout information and a method of correcting the layout information will be described. First, in the placement element designation device 5, as shown in FIG.
From the logical connection relation (flow sheet) of the plant equipment (crushing equipment, piles, etc.) that composes the plant to be designed shown in (a), considering the relation of function, role, connection relation, etc., 1 or Two or more plant devices are selected and classified into units called placement elements (Fig. 4 (b)). Then, for each of the above-mentioned classified placement elements, the relative position (relative coordinate value) and size of each device from the reference point in each placement element, and the connection device such as a conveyor for connecting with other placement elements. The relative position (relative coordinate value) of the connection position from the reference point is input (FIG. 4C). In the subsequent layout design, the layout elements and the connected devices that connect them will be considered for layout on the terrain to be laid out. Although the process by the layout element designating device 5 can be newly performed manually, the process shown in FIG.
The partial logical connection relationship shown in (b) and the relative positional relationship in the placement element shown in FIG. 4 (c) are made into a database, and the partial logical connection relationship of the designated placement element and the past in the database are stored. By performing the matching operation with the partial logical connection relationship, the relative position information in the placement element shown in FIG. 4C can be automatically generated. Next, the arrangement information input device 6 inputs the arrangement information composed of the three-dimensional coordinates (of the reference point) and the rotation angle of each arrangement element designated by the arrangement element designation device 5. That is, each layout element is mapped on the same coordinate system (absolute coordinate system) as the topographic mesh data previously stored in the layout model storage device 11. Then, the arrangement information is stored in the arrangement information storage device 8.

The layout information stored in the layout information storage device 8 is automatically modified by the layout information modification device 7 so as to satisfy the constraint condition and the design standard. The arrangement information correction device 7 has a configuration as shown in FIG. First, the arrangement information acquisition unit 21 acquires the arrangement information stored in the arrangement information storage device 8. Next, the terrain data acquisition unit 22 acquires the current terrain mesh data (before or after formation) stored in the layout model storage device 11. Then, the evaluation value calculation unit 23 calculates an evaluation value from the arrangement information and the terrain mesh data. The evaluation values used are the placement constraint condition violation degree and the connected device constraint condition violation degree.
The placement cost is also used as necessary, and is calculated by the placement constraint condition violation degree calculation unit 23a, the connected device constraint violation degree calculation unit 23b, and the placement cost calculation unit 23c.

Next, an evaluation method in the evaluation value calculation section 23 will be described with an example. First, the placement constraint condition violation degree calculation unit 23a digitizes the placement constraint condition violation degree. FIG. 6 is a plan view showing a state in which the placement elements a, b, c, d are placed in the plant target area, and the solid line connecting the placement elements represents the conveyor which is the connection device. In this example, the arrangement element d is arranged so as to partially deviate from the plant target area. In this way, the part deviated from the plant target region, that is, the area shown by the placement constraint violation part in FIG. 6 is defined as the constraint violation degree regarding the plant target region. In addition, it is necessary to secure a certain area to perform maintenance work for each device after plant placement. The degree of violation regarding this constraint is calculated in the same manner. Further, FIG. 7 is a side view showing a state in which the arrangement elements K, L, M are arranged. In this example, the arrangement element K is arranged so as to be raised above the terrain. Therefore, the degree of violation of the constraint of installing on the surface of the earth is digitized as in the case of FIG. Then, an appropriate weight is applied to the degree of constraint violation regarding the above-described placement, and the added value is set as the degree of placement constraint condition violation.

Connected device constraint condition violation degree calculation unit 23b
Then, for example, the degree of constraint violation concerning the inclination angle of the conveyor connecting the arrangement elements is calculated. If the conveyor tilt angle is too large or if it has a reverse slope, it is not possible to properly carry a crushed stone or other object, so quantification is performed as shown in FIG. 8 to calculate the degree of constraint violation. In the example of FIG. 8, the constraint violation degree is set to increase when the conveyor inclination angle exceeds a certain angle or when the conveyor slope becomes an inverse gradient (negative angle). In addition, for each layout element, there is an empirically desirable plane angle when feeding and pulling out the conveyor, and this is also quantified. Then, an appropriate weight is applied to the constraint condition violation degree relating to the connected device as described above, and the added value is set as the connected device constraint condition violation degree. The placement cost calculation unit 23c calculates the cost associated with plant placement. For example, the sum of the lengths of the conveyors in the plant and the sum of the loads of the unloading and loading soil when the positions of the arrangement elements are determined are calculated. The length of the conveyor is calculated from the connection position of the connection device of each arrangement element. The amount of unloading / importing soil is calculated by taking the difference between each location element whose position is determined and the topographic mesh data.
Take the sum of weights by multiplying the above three calculated values by an appropriate coefficient,
The evaluation value C is used.

Next, the placement element position correction amount calculation unit 24 obtains the correction amount of the placement element position such that the evaluation value C decreases. As a method, the evaluation value C is differentiated by the position vector of the arrangement element, and is corrected in the opposite direction by an amount by which C decreases. That is, x _i , y _i , z _i , θ _i
Where x is the x-coordinate, y-coordinate, z-coordinate, and rotation angle of the layout element i, the vector t representing the position has the layout element number N,

[Equation 1] Can be expressed as Therefore, the correction direction d is

[0025]

[Equation 2] Required by. Since it is not practical to analytically determine a specific numerical value of the correction vector, it is determined numerically. Although a known method can be used for a specific method for effectively (correcting the estimation accuracy) of the correction vector, a basic flow will be described here. In order to calculate each element of the correction vector, each element of the position vector t is slightly changed, the evaluation value is recalculated by the evaluation value calculation unit 23, the change amount of the evaluation value C is obtained, and each of the correction directions d is calculated. Find the element (partial differential coefficient). When the correction direction d is determined, d is multiplied by the correction amount w to calculate the final correction vector. The magnitude of the correction amount w can be obtained at high speed by performing a one-dimensional search for the value of the evaluation value C.

The placement element position correction amount thus obtained is used by the placement element position determination unit 25 to obtain the placement information acquisition unit 2
The placement information is automatically corrected by adding the position of each placement element acquired in 1. The corrected placement information is stored again in the placement information storage device 8. However,
It may be stored in another storage means. The formation surface is determined using the arrangement information corrected as described above, the formation surface data is input from the formation surface input device 3, and the formation calculation device 4 performs the formation calculation, or the formation calculation already performed. It is also possible to modify the operation.

Next, a three-dimensional model is generated using the previously stored terrain mesh data and arrangement information.
In the three-dimensional model generation device 10, the layout information modified by the layout information modification device 7 and stored in the layout information storage device 8 or another storage device, that is, (of the reference point) of each layout element
Coordinate values in the absolute coordinate system of all plant equipment are calculated from the sum of the three-dimensional coordinates, the rotation angle, and the relative coordinate value (vector) of the plant equipment in each placement element. Also, the connection position of the connected device in the placement element is calculated in the same manner.
Then, a three-dimensional model of the plant is generated using the three-dimensional shape data of each plant device and the connected device registered in advance in the three-dimensional shape data storage device 9. Here, there is no problem because the three-dimensional shape of each plant device can be determined regardless of the layout condition, but the final three-dimensional shape of the connected device such as the conveyor cannot be determined until the layout is specified. Here, the model generation procedure will be described taking the case of a conveyor as an example. FIG. 9 is a block diagram of a three-dimensional model generation portion of the conveyor in the three-dimensional model generation device 10. The arrangement information acquisition unit 31 acquires, from the arrangement information storage device 8, data necessary for model generation in the arrangement information corrected by the arrangement information correction device 7. In the case of a conveyor, the conveyor withdrawal position (tail) and the conveyor supply position (head) for each placement element are acquired. Also, in order to determine the three-dimensional shape of the conveyor,
Since it is necessary to properly determine the shape of the pillar as the number of the pillars, the generation rule storage unit 33 stores the pillar setting rule for determining the pillar setting position from the base length of the conveyor. A simple example of this post installation rule is shown below.

"Protrusions are generated at a constant interval from the conveyor head position, and generation is terminated when the remainder up to the tail is equal to or less than a constant interval". That is, in FIG. 10, constant intervals are provided from the conveyor head position toward the conveyor tail position. It is installed with L, stanchion 1, stanchion 2, ..., and the interval SL from a certain stanchion (stanchion 3 in the case of FIG. 10) to the conveyor tail position is S
The generation is terminated when L ≦ L. Of course, other than this, a method of installing all columns at equal intervals is also conceivable. Next, in the three-dimensional model generation unit 34, a three-dimensional model of the conveyor is generated using the data acquired by the arrangement information acquisition unit 31 and the column installation rule stored in the generation rule storage unit 33. Further, at that time, since the grounding position of the pillar of the conveyor to the terrain is required, the terrain data acquisition unit 32 acquires the terrain mesh data from the layout model storage device 11, and the installation coordinate calculation unit 35 calculates the struts and the terrain mesh data. Determine the pedestal ground contact coordinates by calculating the intersection. The three-dimensional model of the conveyor thus generated is stored in the three-dimensional model storage unit 36.

The three-dimensional model of each placement element and connected device generated as described above is stored in the layout model storage device 11 as a layout model together with the topographic mesh data already stored. At that time, The three-dimensional model has a hierarchical structure as shown in FIG. First, the top layer is the entire plant model, which is represented by component element names (placement element names and connected device names) and attribute values such as price and weight. However, no value is set for the above attribute value here. The second layer is represented by the object name (crusher 1, support 1, etc.) of each of the constituent elements and attribute values such as price and weight. Further, the third layer is represented by a graphic name (a rectangular parallelepiped, a cylinder, etc.) and attribute values such as price and weight for each object. Furthermore, the fourth layer is represented by the attributes (length, radius, etc.) of each of the above figures. The attribute values such as the price and the weight are set where the second and subsequent attribute values can be determined.

Next, the group calculation device 13 will be described. When the construction surface is not decided in advance or when the construction surface is changed by modifying the above arrangement information, which arrangement element is installed on the same construction surface from the position of each arrangement element (same height position) By calculating whether or not), the labor for determining the above-mentioned construction surface is greatly improved. Therefore, the group calculation device 13 classifies each placement element into groups to be installed on the same construction surface. The group computing device 13 is configured as shown in FIG. The number of groups input section 41 inputs the number of groups into which the layout elements are classified. The layout element information acquisition unit 42 acquires the installation position of each layout element from the layout model storage device 11. The similarity calculator 44 determines the similarity between the two groups, for example, according to the following calculation rule. Here, the center position of each group is obtained from the center of gravity of the layout elements that make up the group.
Now, assuming that the center position of the group i is (x _i , y _i , z _i ) and the center position of the group j is (x _j , y _j , z _j ), the similarity S between the group i and the group j is Calculate as.

(Equation 3) Here, a and b are parameters and are determined in advance.

The clustering unit 43 performs grouping calculation according to a known hierarchical clustering procedure as shown in FIG. The initial group is set in S1, and the similarity calculation between the groups is performed by the similarity calculation unit 44 in S2. The maximum value of the similarity is calculated in S3, and one group having the maximum similarity is combined in S4. In S5, the number of groups is the number of groups input section 4 described above.
It is determined whether or not the number of groups input in 1 has been reached, and if the number of groups is greater than the number of input groups, the processing from S2 onward is repeated. The group information determined in this way is stored in the classification information storage device 14 by the group information determination unit 45. The creation surface is determined using the group classification information obtained in this way, the creation surface data is input from the creation surface input device 3, and the creation operation is performed by the creation operation device 4, or the creation operation already performed. It is possible to modify the operation. In that case, of course, it is also necessary to regenerate the three-dimensional model by the three-dimensional model generation device 10.

Next, the layout model storage device 11
The display and output of the layout model stored in will be described. The layout model display / output device 12 sets an arbitrary viewpoint position with respect to the layout model, converts the layout model into two dimensions by known projection conversion processing and clipping processing, and displays it on the screen. At that time, three-dimensional rendering processing such as hidden surface, hidden line processing, shading, and ray tracing can be performed as necessary. Further, by using the group classification information stored in the classification information storage device 14, it is possible to perform color-coded display for each group, display only a specific group, and the like.

Finally, the estimation calculation part will be described. The estimation calculation device 15 has a configuration as shown in FIG. First, the 3D model acquisition unit 51 acquires the configuration data of the 3D model from the layout model storage device 11. The configuration data has the hierarchical structure as shown in FIG. 14 as described above. The model attribute calculation unit 52 refers to the price and weight values that are attribute values in order from the uppermost layer of FIG. 14, until the prices and weights of these elements are found in the price / attribute data storage device 56. Follow the depth direction. If the price and the weight are registered in the price and attribute data storage device 56, the values are copied and, conversely, added in the shallower direction of the hierarchy to obtain the value. At that time, in the case of an object whose length changes, such as a chute or a strut, at the figure level that constitutes it,
The price and weight are determined by a predetermined calculation formula. The model classification unit 53 collects the attribute values for each layer in FIG. Then, the model price calculation unit 54 calculates the model price using the calculated price, weight, and price calculation formulas for each attribute value stored in advance in the price calculation rule storage unit 57. The price calculation formula includes, for example, a calculation formula of an installation cost for installing the layout element as a price related to the weight attribute. The estimation result thus obtained is displayed by the model price output unit 55 on the estimation display device 1
It is sent to 6 and displayed.

The following effects can be expected by the method and apparatus described above. The placement information correction device 7 automatically corrects the placement information in the direction of decreasing the evaluation value of the placement information, and generates a three-dimensional model using the corrected placement information. Layout design can be done quickly and automatically. Also, when generating and storing the above three-dimensional model,
By generating and storing attribute values such as price and weight at the same time, estimation work can be performed quickly and automatically. Further, since it is possible to determine or modify the construction plane by using the arrangement information corrected by the arrangement information correction device 7 or the group classification information generated by the group calculation device 13, each of the formation plans can be determined. Both cases can be taken before or after the function placement decision is made.
